6 Claims.

This invention relates to looms and more particularly to means forleveling the heddle eyes in a loom provided with a jacquard head.

An object of the invention is to provide a device which will facilitateleveling the heddle eyes.

In actual practice the warp is drawn in through the heddle eyes and theheddles are attached to the jacquard hooks by means of neck cords. Priorto starting the loom it must be determined that all eyes are on the samelevel, otherwise an uneven shed will be formed which would interferewith the travel of the shuttle and thereby cause a number of fabricdefects.

Another object of the invention is to provide such a device which issimple to construct, easily applied to any type of loom and simple tooperate.

Other objects, advantages and novel features of the invention will beapparent from the following description of the illustrative embodimentshown in the accompanying drawing, in which:

Fig. 1 is a perspective view of a portion of a loom showing the eyeleveling device in position;

Fig. 2 is an end view of the leveling device; and

Fig. 3 is a front view of the leveling device.

Fig. 1 illustrates a portion of a loom adapted to be equipped with ajacquard head comprising the usual side girts l and I l, arch l 2 andcomber board l3. The comber board is shown attached to the arch.

The leveling device comprises a bar l4 extending transversely of theloom and just in front of the space to be occupied by the heddles. Thebar [4 is shown provided with lugs l5 and [5. The lugs are adapted tosupport the bar on the loom sides. Fig. 1 shows only one heddle IT inposition. It is understood however that all the heddles will have beendrawn in and the figure is only for purposes of illustration. The heddleis urged downwardly by means of a weight or lingo l8.

Bar M has attached to it a member such as block l9. Block [9 is providedwith a hole only slightly larger and of the same configuration as across-section of bar l4. Bar I4 is passed through this hole and in thismanner block I9 is slidably mounted on bar l4. Some fastening means suchas a set screw 2| on block l9 may, if desired, be provided to hold blockI9 in any desired position on bar I4.

A generally L shaped rod is shown mounted on block l9 and is preferablyvertically slidable. The rod 22 passes through an aperture in block I9and may be held in any vertical position by means of set screw 23. Thehorizontal portion of the rod transversely movable member, adapted to beheld 22 is shown bifurcated at 24 and of such length as to be capable ofengaging heddles ll.

In operation, the L shaped member 22 is placed in the desired position,the heddle I1 is placed between the prongs of the bifurcation of member22 and drawn upwardly by means of the usual neck cord 25 until the lingol8 engages the lower portion of the bifurcation 24. having previouslybeen passed through the comber board I3 is now made fast at its upperend to its jacquard hook, not shown.

While only one embodiment has been shown provided with a jacquard headcomprising a' transversely movable member, adapted to beheld fixedly atcertain desired positions, means to support said member at a constantlevel, and a vertically movable member carried by said first namedmember, adapted to be held fixedly at certain desired positions andadapted to engage the heddles of said loom.

3. A device for leveling heddle eyes in a loom provided with a jacquardhead comprising a transversely movable member, adapted to be heldfixedly at certain desired positions, means to support said member at aconstant level, and a generally L shaped vertically movable member,carried by said first named member, the horizontal portion of said Lshaped member being adapted to be held fixedly at certain desiredpositions and adapted to engage the heddles of said loom.

4. A device for leveling heddle eyes in a loom provided with a jacquardhead comprising a transversely movable member, means to support saidmember at a constant level, and a generally L shaped vertically movablemember, carried by said first named member, the horizontal portion ofsaid L shaped member being bifurcated and adapted to engage the heddlesof said loom.

5. A device for-leveling heddle eyes in a loom provided with a jacquardhead comprising a The neck cord' fixedly at certain desired positions,means to support said member at a constant level, and a generally Lshaped vertically movable member, carried by said first named member,the horizontal portion of said L shaped member being bifurcated andadapted to engage the heddles of said loom.

6. A device for leveling heddle eyes in a loom provided with a jacquardhead comprising a horizontal bar supported by said loom, a member 1slidably carried by said bar, locking means to hold said member in afixed position, a generally L shaped vertically slidable member carriedby said first named member and locking means to hold said verticallyslidable member in a fixed position, said last named member having ahorizontally disposed bifurcated portion adapted to engage the heddlesof said loom.
